What is 3D movement tracking?

three -dimensional (3D) tracking of movement is an act of capturing movement data by actors and actresses. It is similar to filming a person that moves around, but the difference is that instead of the shots that can be played, 3D viewing of movement records movements, so it can be used for 3D rendering programs. Carrying requires special hardware, such as suits and small tracking units, but some systems need a camera to capture. The subgroup of the movement of the capture, called the capture of performance, deals with limbs and face elements. When shooting, the shots can only be monitored, while the movement of movement is a digital movement model that can be applied to 3D characters on the computer. This is most commonly used by the film industry in creating 3D animated films or when computer models require complex movement. Motina Tracking is also used by an army to create virtual exercises and engineers to control machines. Special hardware is required to perform 3D movement. Have been in the pastActors and actresses equipped with suits and small tracking units and their movement watched the camera. This hardware is still used frequently, but more advanced systems are able to capture movement data without the need for followers, known as marker -free monitoring. A special camera is still needed to convert all movements to digital signals and information.

The practice of watching 3D movement deals with how the limbs and torso move, but not with finer details of human movement. Power capture is used for finer details. This type of tracking gets data from finger and face movements, so artists controlling the 3D model have complex data about these movements. Without this information, artists have it to create facial expressions and fingertips from zero, which can lead to unpleasant expressions or stiff hands and fingers.

before 3D movement is available was available animated film artists in the past to SMovement Like a system called rotoscoping. The actors and actresses were filmed by performing movements and speaking lines according to the script. The artists would then take the film and draw each films individually. This resulted in a more realistic animation, because all movements were based on real people. Most of the main animation companies, before the arrival of 3D movement, used rotoscoping.
